This book is intended for Earth science specialists using geophysical methods, which are applicable to both reservoir studies and civil engineering. In each chapter, the reader will find theoretical concepts, practical rules and, above all, concrete examples of applications. For this reason, the book can be used as a text to accompany course lectures or continuing education seminars.Contents: 1. Methodology for the study of geotechnical problems. 2. From the petroleum field to civil engineering. 3. Theoretical overview of seismic and acoustic techniques. 4. Reflection seismic. 5. Refraction seismic. 6. Well seismic. 7. Acoustic logging. 8. Examples of hydrocarbon field and civil engineering studies. 9. Radar. 10. Role of well logging in geotechnics. 11. Logging and soil mechanics. Bibliography. Index.
This book examines the evolution of geophysical methods for exploring sedimentary basins by describing the internal structure and the nature of the formations found in such basins. The applicability of non-seismic methods is defined together with the conditions for their use. The seismic reflection method is fully described, distinguishing between the basic methods for handling routine problems and their adaptation to more specific or complex problems. The author then finally covers the emerging techniques of the future. Each fully illustrated chapter is a complete topic, easy to read with the mathematical derivations banished to the appendices." - back cover.
In this work, I have attempted to give a coherent exposition of the theory of differential forms on a manifold and harmonic forms on a Riemannian space. The concept of a current, a notion so general that it includes as special cases both differential forms and chains, is the key to understanding how the homology properties of a manifold are immediately evident in the study of differential forms and of chains. The notion of distribution, introduced by L. Schwartz, motivated the precise definition adopted here. In our terminology, distributions are currents of degree zero, and a current can be considered as a differential form for which the coefficients are distributions. The works of L. Schwartz, in particular his beautiful book on the Theory of Distributions, have been a very great asset in the elaboration of this work. The reader however will not need to be familiar with these. Leaving aside the applications of the theory, I have restricted myself to considering theorems which to me seem essential and I have tried to present simple and complete of these, accessible to each reader having a minimum of mathematical proofs background. Outside of topics contained in all degree programs, the knowledge of the most elementary notions of general topology and tensor calculus and also, for the final chapter, that of the Fredholm theorem, would in principle be adequate.
